— Your answer is partially correct. Multiple-Concept Example 3 provides some pertinent background for this problem. Suppose a single electron orbits about a nucleus containing two protons (+2e), as would be the case for a helium atom from which one of the naturally occurring electrons is removed. The radius of the orbit is 2.92 × 10-¹1 m. Determine the magnitude of the electron's centripetal acceleration. Number i 5.9E23 Units m/s^2
